ICE SCORING MACHINE Application filed January 23, 1928. Serial No.248,674.

My invention relates to improvements in ice-scoring machines such asVare used for d automatic in operation, thus requiring a minimum ofattention when in use and effecting a tremendous saving in overheadexpense.

A further object of the invention resides in the provision, in a machineof this class, of means actuated by the work for effecting engagement ofthe same to certain of the scoring elements.

Another object is to incorporate in an ice scoring machine, awork-actuated stop for ielnporarily halting the movement of the work inone direction at a given point and a subsequently operable carrier formoving the work in another direction to present it to scoring elements.

A further object of the 'invention resides in the provision, in amachine as characterized, of a work-actuated stop and a reciprocalwork-carrier .movable transversely of the n rmal path of the work7 whichcarrier has means for moving the stop out of work-engaging position sothat the work can be moved in its original path at a predetermined time.

A still further object of the invention resides in the provision, in amachine of this class, of combined cushioning and guide means for awork-carrier.

till another object is to provide an icescoring machine having awork-carrier, the driving means of which is initially thrown intooperation 3y woilr-actiiated means, and which is kept in operation for apredetermined time and subsequently thrown out of operation bycarrier-carried means.

rl`lie invention also resides in certain novel features of construction,combination, and aiangement of the various parts and in modes ofoperation, which will readily mani- .lves to those skilled in the art intion and appended claims, reference being had to the accompanyingdrawings forming a part of this specification.

In accordancewith the patent statutes,'the now preferred embodiment ofthe invention has been illustrated and will be described. However, it isto be understood that the invention is capable of other mechanical eX-pressions within the spirit and scope of the appended claims.

The frame Referring specifically to the drawings, wherein the samereference characters have been employed to designate the same parts inall views, the machine comprises a frame including longitudinal sills 1,which are spaced apart, as indicated in Figure 3, and from which risethe vertical posts 1, 1b, which are shown in Figures 1 and 2. The posts1a, are bound by cross pieces 1C, 1d. The cross pieces 1c are locatedintermediate the ends of the elongated upstanding posts 1a. Theintermediate cross pieces 1c are shown in Figure 1, while one of suchcross pieces is shown in cross section in the broken side elevationalview, Figure 2.

The tie or cross pieces 1d are disposed at the upper ends of theelongated frame posts 1a, as clearly indicated in Figures 8, 4t, 5 and6, one of said top cross pieces 1d being also shown in Figure 8.

Figures 1, 2, 5 and 6 illustrate longitudinal connecting bars or members1e for connecting the tops of the posts 1a, while Figure 5 shows a crosspiece 1I intermediate the ends ofY longitudinal frame members 10 forconnecting the same.

In connection with the sills 1 and the upstanding elongated posts 1a, itis desired to state that these members are ireferably of angle, orL-Shaped, cross section so Vthat the sills will present inturned flanges(see Figure 3) for supporting an elevator, while the members 1ZLconstructed in angular cross section, as aforesaid, may serve to guidethe elevator in its movement.

ln connection with the frame of the machine, reference has been made toupstanding posts 1b. rllhese are shown in the elevational views, Figures1 and 2. and from an inspection of Figures 1, 2, 3 and 5, it will beevident that such posts or members 1b are disposed at but each side ofthe frame. Four of such posts or members 1b ar-e illustrated, 2 at eachside, and their tops are bound together by longitudinal bars 1g, whichare suitably connected to the adjacent elongated upstanding posts 1a, asindicated in Figures 1 and 2.

The foregoing concludes the description of the machine frame proper.Manifestly the cross pieces 1c etc. can be multiplied, if

desired, without the exercise of invention. l have shown a minimumnumber of such ci oss pieces 1c so as not to obscure the working partsof the machine.

The scoring saws At each side of the frame and journalled in bearings 2bmounted on the posts 1a, substantially mid-way their ends, are sawshafts 2.

Figure 5 clearly indicates that the saw shafts 2 extend a substantialdistance beyond the intermediate pair of upstanding posts 1a. rFhisligure also shows that one of said saw shafts 2 has a driving connectionwith the armature shaft of a motor 3, which is suitably mounted upon thelongitudinal bar 1g, (Figure 1) which is supported by the shortupstanding posts 1b at one side of the frame of the machine.

Still referring to Figure 5 and incidentally to Figures 1 and 2, it willbe manifest that the second saw shaft 2 is driven from the other sawshaft by means of a chain la trained over rocket gears 4t which arekeyed to the respective saw shafts 2. rlhe circular' saws 5, (shown inFigures 1, 2, 8. l and 5) are keyed to the shafts 2, or otherwisesecured thereto, and the peripheries of such saws extend inwardly of theframe into the path of the elevator to act upon the ice carried thereby,all of which will be referred to more in detail hereinafter.

Referring particularly to Figures 1 and 3, and incidentally to the topplan view, Figure 5, it will be noted that each of the horizontal sawshafts 2 has keyed thereon a beveled gear 2c, which meshes with thebeveled gear Ga at the upper end of a vertical shaft 6. This shaft isjournalled in bearings 6C, which are carried by the longitudinal framemembers 1g and the subjacent sill members 1. Figure 3 very clearly showsthat there is a shaft 6 at each side of the frame and also that suchshafts carry saws 7 keyed thereon, the peripheries of which saws 'lextend into the space within the frame, as

indicated in Figure 5. rlhe saws 7 are disposed so as to score the icelongitudinally it is carried through the machine by the conveyor bed 11,11, which will be dealt withmore particularly later on.

The ce omweg/or Figure 1 shows one of the vertical saw shafts (3 asextending beyond its lower bearing 6 and having keyed upon its end abeveled gear (il)` which beveled gear meshes (Figure 3) with the cone orbeveled gear portion S" of sprocket 8fL which is keyed upon the shaft 8.Still referring to Figures 1 and 9i it will be manifest that the shaft 8is carried` in suitable bearings secured beneath and transversely of thesill members 1.

rl`he shaft 8 (Figures l and 3) is the drive n H or) shaft for theconveyor 11, 11a, referred to incidentally hereinbefore. A chain 9 fromthe sprocket Vgear 8a (Figure 3) extends around a sprocket gear 10a on aprojected end 10 of one of the drum shafts which carry the sprocketdrums 10b. Over the sprocket drums 10b are trained the side chains 11 ofthe conveyor which is completed by the cross pieces 11a connecting saidchains and secured thereto in a usual or any preferred manner. Theconveyor .is driven in the direction of the arrows` shown in Figures 1and 2, so as to convey the ice first past the opposed horizontallydisposed saws 7 on the vertical shafts 6 so that the ice will belongitudinally scored at each side in a common plane. After being actedupon by the saws 7 the ice is carried into the enclosure defined by theupstanding posts 1at to be lifted by the elevator 12, which is locatedtherein, so that the saws 5 will act upon the ice to score it verticallyin the upward movement of the elevator.

Figures 1, 2 and 5 illustrate gear boxes or housings 2a carried by theshafts 2 for enclosing the beveled gears 2C, 6a. e

Referring to Figure 3 it is immaterial whether the beveled gear Sb andsprocket 8a are separate or integral. The main point is that they befast on the shaft 8.

The elevator The elevator 12 comprises a rectangular frame includingcorner posts 12C, the tops of which are connected by transverse andlongitudinal bars-12d, 12e, respectively.

Figures 3 -and 1-- and the broken side elevational view, Figure 2, showthat the corner posts 12c of the elevato-r have short longitudinally andinwardly extending flanges or feet 12 which normally rest, (Figure uponthe inturned flan ges of the sills 1 of the frame,

with their top faces or surfaces slightly below the plano of the crosspieces 11a of the top flight of the conveyor 11, 11a and slightly to oneside of the same so that when the elevator is lifted the cake of icewill be lifted up from the conveyor 11, v1121. lt is understood, ofcourse that the ice cake will project laterally at leach side of theconveyor so as to overlie said elevator feet 12.'

Ice for commercial purposes is usually frozen in tapered containers andas a result, the blocks of artificial ice are tapered lengthwise, and inthe accurate scoring of such blocksthis taper is to be considered. Myinvention comprises means to compensate for this taper during thetransverse scoring of such blocks while carried by the elevator 12, toposition the transverse score marks perpendicular to the centrallongitudinal axis of the block for symmetrical'transverse subdivisionthereof. In the illustrative embodiment of my invention this means isprovided by forming the elevator 12 with the lower front endl thereofraised slightly (approximately one half inch if the block is one inchhigher at its large end than at its small end, as is usual) to positionthe longitudinal axis of the block perpendicular to the planes of the'scoring saws.

Elevator operai/ing mechanism The elevator lifted by means of a rack bar13, which 'is secured to an intermediate top cross n member 153i and 6)as indicated 12a. The rack bar 13 extends upwardly through theintermediate frame cross bar 1f (Figure 5) and through a casing 1licarried by said cross bar 1f. W ithin the casing 111 entends the end ofa shaft 17 on which is keyed a spur gear 17@ which meshes with the teethof the rack bar 13. A roller 23 journalled on a short shaft carried bysaid housing 14 bears against the back of the rack har, thus,maintaining the saine in meshing engagement with the gear 17e.y

The shaft 17, which carries the spur gear 17e, is journalled in bearingsprovided by housing lil (Figure and in a bearing H carried by the endcross bar 1d (see Fig. 9).

Figures 1, 2, 3, 5 and 9 illustrate that the outer end oe the shaft 17,which projects be- (Figures 1, 2, 3, t, 5

yond the xit end of the frame, is provided with a cup-like ily wheel17a, which is keyed or otherwise rigidly secured to said shaft.

Loosely mounted upon the shaft 17 and adjacent the cup-like fly wheel 17is a sprocket gear 17C, which has a marginal laterally eX- tendingflange 17 d (see Fig. 9) which is inwardly beveled to engage thecorresponding bevel of fly wheel 17 a.

The matingly beveled flanges of the fly wheel and sprocket gear 17a,17C, respectively,

are kept normally separated by means of a coil spring Q, which encirclesthe shaft 17 and bears against said elements for this pur- 1 h P L pose.Trie fly wheel 11 and the sprocket ear 17C constitute a friction clutchthe r 1 sprocket gear 1i@ being the driven element receiving itsconstant rotation from a shaft 16, which is journalled in bearings 16cmounted upon frame members 1d at one side of the frame and which has asprocket gear 16? which drives the sprocket gear 17c through a cha-in16d (see Fig. 3).

The shaft 16 is constantly driven by means of a belt 15 passing around apulley 2e on the subjacent horizontal saw shaft 2 and a pulley 16 on theinner end of the shaft 16 which projects beyond the inner upstandiiig iposts 1a.

Automatic @luto/7i control ,for elevator dri/ve means The sprocl-:etgear 17Cn which is the normally driven element oi the clutch 17, 17u isactuated into driving engagement with the ily wheel 17 throughinstrumentalities, which are set into operation by the cake of ice whenit is carried by the conveyor to a centered position within the frame 1,1a and the elevator 12.

In carrying out this feature of the invention, I provide, as indicatedin Figures 9 and 10, the bearing H of shaft 17 with a cam end H.Adjacent said bearing cam li and between the same and the loose sprocketclutch element 17C is a loose sleeve i having a cam end J opposed to thecani H" of the bearing H. lt will be manifest that rotation of the loosesleeve J in one direction will throw the same axially along the shaft 17to force the loose sprocket 17c into driving engagement with the flywheel 17, thus putting the shaft 17 in motion. Obviously this willactuate the rack bar 13 to lift the elevator 12.

A lever arm 17b is rigidly carried by the sleeve J and this arm 17b isadapted to be swung by a` star gear 19a a suii'icient distance to engagethe clutch elements 17 a, 17C. The relationship of the lever arm 17b andstar gear 19a is shown in Figures 1, 2, 3, 5 and 8.

rThe star gear 19"L is mounted on the outer end of the stub shaft 19,which is journalled in a bearing 19, mounted upon one top longitudinalframe member 1E, as indicated in Figure 5. rThe star gear 19L isdiametrically opposite the arm 17b of the sleeve J. rllhe opposite endof the shaft 19 has a disk 19D thereon, there being any conventional orpreferred form of one way drive, as for example, the pawl and ratchetdrive connection 19k, 19m between the shaft 19 and said disk 19", shownin the detail view, Figure 13. rlhe pawl and ratchet drive 19k, 19m isadapted to actuate the shaft 19 when the disk is moved in a clockwisedirection, as viewed in Figure 8. The disk 19b is provided with a radialarm 191 (which may be provided with a roller 19e for engaging thecam-rod 18 as best shown in Fig. 5), which normally rests against thebeveled upper end 18 of a rod 18, which is carried by a cross member ofthe elevator 12, as indicated in the detail view, Figure 12.

Figures 1 and 5 clearly illustrate that the shaft 19 is provided with acoil spring 19C, having its outer end anchored, as at 19c to the bearing19. The inner end of the spring 19e is suitably connected to urge thearm 19d in a counteiclocl wise direction as viewed in Fig. 8, as byextending into a surface recess 19f in the surface recess 19h in theadjacent face of the disk 19", as shown in Figure 13. lt is believed tobe obvious that the action of spring 19c is to return the disk 19b withits arm 19d to the normal position Vshown in full lines in Figure 8,after the same has been actuated to the dotted line positions (Figure 8)by the action of the rod 18.

Manifestly, upward movement of the rod 18 results in the actuation ofthe arm 19d to the lirstdotted line position in Figure 8. This rotatesthe shaft 19 in a clockwise direction and likewise the star wheel 19Lwhich is keyed thereon. This, of course, results in the swinging of thearm 17h in a counterclockwise direction to a slight degree, thus,forcing the sleeve J to bring the clutch elements 17a, 17c together soas to drive the shaft 17 with its spur gear 17e so as to draw theelevator up through the engagement of the' spur gear 17e with the rackbar 13.

lt is important to observe that the arm 19d will maintain theintermediate or lirst dotted line position, Figure8, as the `rod 18 ismoved upwardly by the elevator. As a result, the clutch elements 17 a,17c will be held in driving engagement and the shaft 17 will continue torotate.

Referring to Figures 1, 2 and 12, it will be noted that the elevator isprovided with a depending trigger member 183, pivoted intermediate itsends, and having its inner end provided with a gear segment C meshingwith a corresponding gear segment B of a lifting arm 18C, which engagesthe lower end of the rod 18 (Figure 8) as shown in Figure 12. Themembers 18h, 18c are pivoted on cross rods A extending between thelongitudinal members 12e of the elevator frame. The trigger or arm 18bis extended laterally and downwardly in a positionto be engaged by acake of ice as it reaches a point adjacent the discharge end of theframe. Manifestly, upward swinging of the trigger 18h, will through theengagement of the gear segments C, B, swing the arm 18C upwardly to liftthe bar 18. This causes the beveled upper end 18 of said bar 18 toactuate the arm 19d upwardly all as described hereinbefore. Thus,through the star wheel 19a and arm 17h the sleeve J is actuated toengage the clutch elements 17a, 17C. The previously described rotationof shaft 17 results.

Upward movement of the elevator continues until the cam 18a of the rodor shaft 18 engages the arm 19d and moves it to the uppermost dottedline position Z shown in Figure 8. TWhen this occurs the shaft 19 willhave been rotated far enough to cause the star wheel prong, whichengaged the arm 171,to pass beyond the same permitting the arm to movein a clockwise direction (Figure 8) under the influence of the spring Qacting through the sleeve J and the cam portions J, H of the sleeve Jand-bearing H, respectively, the resulting release of the clutch 17, 17,allowing the elevator 12 to descend by gravity, carrying with it the camrod 18. rlhe action of the spring 19c causes the disk 19b to immediatelymove in a counter-clockwise direction with its arm 19d to assume thelowermost dotted line position in Figure 8 as soon as the cam 18a iscarried from under the arm 19d. However, the shaft 19 will remainstationary and the star wheel 19a consequently will remain intheposition to which it was actuated by the engagement of the cam 18a withthe arm 19d. This is due to the pawl and ratchet drive connectionbetween disk 19b and shaft 19 (Figur-e 13).

The arm 19d is retained in its lowermost dotted line positionA Fig. 8)until the block of ice underlying the trip lever 18b is carried out fromunder the latter, allowing the cam rod 18 to drop still lower and carryits can surface 18 under the arm 19d sothat it may move to the full lineposition shown in Fig. 8, to arrange the elevator control structure inposition to be actuated bythe nent block of ice raising the lever 18h.Thus the lever 18", with its associated parts, when actuated by a blockof ice, serves to initiate one operation of the elevator mechanism,andthen to prevent re-operation of the elevatormechanism during movementof the ice from the elevator. YWith the four-pronged star wheel shown,it is obvious that the entire rotation. tiereof caused by the camsurfaces 18.- and 18L1 for one operation of the machine will he onequarter revolution. Y

As above mentioned, when arm 1'?b disengages from the prong of the starwheel the clutch drive is broken and the elevator immediately descendsto Adeposit the ice upon the conveyor 11, 11a so that it can be carriedout of the machine. f

Buffer check or ora-e for descending @Zee/c1507 As shown in Figures 1,4,and 6 there is provided a main hydraulic brake chamber 21, which issecured to one of sill members 1, as indicated at 21. From this chamber21 leadA pipe lines 21b which connect with piston chambers 21, which aresecured to the frame by means of keepers 21k. Working in the cylinders21a are pistons 21c (see Fig; 4), which are securedby brackets 21e totwo diagonal corners of the elevator frame, as shown in Figure 6.Manifestly, when the elevator descends the pistons working in thechambers 21a will act as a brake or cushion to avoid a bump. lt is alsoto be noted that the pistons 21, working in the chambers or cylinders21a act as guides for the elevator 12.

. .past it by the members 12b as hereinafter de- [ce and elevatorcontrolled stop As the ice moves into the frame carried by the conveyor11, 11a, it is manifest that it is very desirable to prevent the icefrom slipping past the elevator before the same can operate. In order topr-event such a thing from taking place I provide at the exit end of theframe a pair of guides 22a for receiving a vertically slidable cross bar22. l/Vhen the cross bar 22 is in its lowcrmost position, as shown inFigur-es 1 and 8 the cake of ice will be intercepted and prevented frompassing out of the frame, which is to say, past the posts 1a at the leftof Figure 1. The stop bar 22 is adapted to be held in elevated positionout of the path of the ice block by means of a latch 2O which is carriedby a mounting 20a, (Figures 1 and 3) there being provided a control arm20", which is 'swingable to retract the latch to permit the stopbar 22to drop. Figure 1 illustrates that the control arm 20b of the latch haspivoted at its outer end and slightly beyond the side of the frame, theend of a rod 20c, which is also shown in Fig. 6. Thus movement of thisrod 2Oc toward the entrance end of the machine swings the control arm20h and retracts the latch member'2() to allow the stop-bar 22 to fallfrom its elevated position. According to'my invention, this operation isto beeected by work-actuated means, and in thefreferred embodimentof myinvention this means comprises a depending shoe or element 20e, showndiagrammatically in Figs. 1, 5 and 6, suitably .connected to the rod 20,as by elements l2Od and 25, so that movement of the shoe 2Oe by a blockof ice will cause the latch member 20 to be withdrawn.` l

f Figs. 'Z' and 14 show an illustrative construction` in'which the shoe2Oe is pivoted to the frame of the machine at 2()f` in position to beengaged and pivoted by a block of ice entering the elevator. As shown,the shoe 20e is pivoted at its center and as the ice strikes and movesits enlarged, yheavy lower end toward the exit end of the machine, itsupper end moves 'in the opposite direction, carrying with it the rod2Odv to which it is connected. The rod 2Od is in turn connected to anarm 25 pivoted at 2()g to the bracket 27 so that the movement of the rod2Od causes the arm 25 to swing in a clockwise direction as viewed inFigs. 1 and 7. The rod 2Oe is likewise connected to the arm 25, so thatthe movement of the arm 25 lifts and pulls the rod 20c to retract thestop 20. 1n the embodiment shown the weight of the r0d'20c and the heavylower end of' the shoe 2Oe are sufiicient to impart counter-clockwisemovement to the arm 25 as viewed in Fig. 1 and return thelatch 20 tooperative position after the ice has passed from under the shoe (andafter ther stop-bar 22 has been lifted scribed), but it is obvious-thatother'mechanical means can be employed to control the latch member 20,and that in such case, any suitable means, as a spring or the like, canbe used to return the latch to its operation position afterfretraction.

Thus, broadly considered, my invention contemplates the provision of astop mechanism to halt the ice-block in position to be raised by theelevator, means whereby the stop mechanism is rendered ineffective toallow the ice block to move from the elevator after scoring, andwork-actuated means to render the-stop mechanism effective for stoppingthe next block; and in the preferred embodiment of mv invention thiswork actuated means is disposed to be actuated by the ice block enteringthe elevator.

From the foregoing it will be clear that in the illustrative embodimentshown, the ice block entering the elevator, by. swinging the finger orshoe 2Oe in a clockwise direction retracts the latch 20 and allows thestop bar 22 to drop to the position shown in Fig. 1.

Bar 22 remains in such position until the cake of ice has been lifted bythe elevator. Figure 6 shows that the elevator adjacent the dischargeend is provided with bottom extensions 12b, which are adapted tointercept the stop bar 22 and lift the same to a point above the latchso that when the cake of ice is lowered in the elevator there will be noobstruction to prevent the same from being carried out by the conveyor11, 11a through the discharge end of the machine, which is at the left,as viewed in Figure 1.

Manual clutch modification Figure 11 shows a modified form of theinvention and particularly, a manually controlled clutch for thesectional elevator drive shaft 17X, 17Y. Section 17X may be driven fromshaft 16 (see Figs. 3 and 5) by a'chain over sprocket 17W. Clutchelements T and S of shaft sections 17X, 17y serve to drive shaft section17y when the same is moved endwise through lever L to bring T, S intoengagement. Lever L is pivoted as at P to a frame member 1X. The rackbar'13, of Figure 4;, is dispensed with and instead a cable O, attachedto elevator 12, is wound on pulley M of shaft section 17Y.
